Key Features
- OEM-Spec Construction — Manufactured to Husqvarna's original engineering tolerances, ensuring the arm pivots, locks, and aligns exactly as the original unit did at the factory.
- Direct Drop-In Replacement — Engineered to match the original mounting points and hardware interfaces on the MS360, TS70, and TS90, so the arm seats correctly without modification.
- Broad Tile and Masonry Saw Compatibility — A single part that covers three Husqvarna tile and masonry saw models, making it straightforward to identify and order the correct component.
- Restored Cutting Accuracy — A properly functioning cutter arm maintains blade path alignment through the full cutting stroke; a worn or damaged arm introduces drift and inconsistent depth, degrading cut quality on tile, stone, and masonry.
- Genuine Husqvarna OEM Part — Supplied as an authentic Husqvarna component, giving you confidence that material grade, geometry, and load ratings match the original design intent for your saw.
The cutter arm is the structural pivot assembly that guides and supports the blade head through its cutting arc on a tile or masonry saw. It bears the load of the motor and blade during each pass, so its rigidity and alignment directly determine cut straightness and depth consistency. When the cutter arm becomes bent, cracked, or worn at its pivot points, the blade path deviates, resulting in inaccurate cuts, increased blade wear, and potential material waste — making prompt replacement essential to maintaining productive, accurate sawing.
